1 Claim.

The present invention relates to screen printing tables.

The principal object of the invention is to provide a screen printingtable having an improved form of heating means for quickly drying thescreen printed material.

Another object is the provision of a screen printing table combining asure source of heated air uniformly delivered throughout the entirelength and breadth of the screen.

A further object is the provision of a screen printing table including apositive drying means utilizing steam heat which need not be PIOdllCedin high quantity during a given period of time.

Still another object is the provision of drying means for screenprinting tables of conventional form and design, said drying means beingadapted to any conventional screen printing table.

These and other objects are attained by mechanism shown in theaccompanying drawing in which- Fg. 1 is a perspective view of a screenprinting table incorporating the drying means herein described andclaimed, said table and the screen thereon being broken away to exposethe heating elements;

Fig. 2 is a longitudinal vertical section through the screen printingtable shown in Fig. 1; and

Fig. 3 is a transverse vertical section of the table top, said sectionbeing drawn on the line 3--3 of Fig. 2.

Referring now to Fig. l, it will be seen that the table I is providedwith a metal screen top I.I which is covered with an intermediate layerof felt l2 and a top layer of muslin I3. It will be noted that belowscreen II is a chamber or compartment I4. Reference to Figs. 1 and 2will show that this chamber is coextensive with the screen and that itis open to the screen as well as to a box I situated at one end of saidtable.

Carried in the chamber I4 is a steam pipe I6 which is connected at itsinlet end I1 with a source of steam supply (not shown). It will be notedthat the pipe is wound back and forth in the chamber, forming sixlongitudinal portions substantially equidistant from each other. It willalso be noted that box I5 contains a blower I8 operated by means of anelectric motor I9 in the usual manner. One Iof the sides of box I5comprises a screen 2U through which the blower draws in fresh air.Arrows 2| indicate the direction taken by the fresh air drawn in by theblower after it leaves the blower. It will be seen that the fresh air isblown up into chamber I4 where it circulates around steam pipe I6. Inthe chamber, the fresh air becomes heated and still under the influenceof blower .I 8, it is forced up through screen I I, layer of felt I2,layer of muslin I3 and the work (not shown) It will be seen that asubstantial improvement in the art has herein been shown and described.Variations which may occur to men skilled in the art may be incorporatedinto the device without departing from the principles of the invention.For example, the steam pipe may be wound in different ways from thatshown in the drawing. Also, instead of a steam pipe, electric heatingmeans or other heating means may be used. The blower I8 need not besituated at one end of the table but instead it may be situated in thecenter thereof. In place of a blower, any air pumping means may be used.

I claim:

A screen printing device including a table having a screen topcomprising a screen, a felt layer covering said screen and a layer ofmuslin covering said felt, a chamber immediately below said screen topand coextensive therewith, said chamber being open to said screen top, asteam pipe in said chamber which loops back and forth to form aplurality of horizontally disposed portions of substantially equallength, extending from one end to the other of said chamber, a blower atone end of the table communicating at its inlet end with the atmosphereand at its outlet Aend with said chamber, whereby fresh air is drawninto said chamber where it is heated by said steam pipe and the heatedair is forced out of said chamber through said screen top.
